CUFF-BUTTON.

SPECIFICATION forming part of Letters Patent No. 256,015, dated April 4, 1882.

Application filed January 31, 1882. (No model.)

To all whom it may concern:

Be it known that I, DAVID LUBIN, of Sacramento City,in the county of Sacramento, and in the State of California, haveinvented certain new and useful Improvements in Cuff-Buttons 5' and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, making a part of this specification.

My invention relates to cuff and collar buttons; and it consists in certain new and use- (ful improvements in the manner of constructing the several parts and of uniting the same together, as hereinafter more fully set forth.

In the accompanying drawings, forming a part of this specification, Figure l is a perspective view of my improved button, the parts being united together. Fig. 2 is a view of the parts detached, shown partly in side elevation and partly in vertical section. Fig. 3 is a similar view, showing the parts united or screwed together; Fig. 4, a perspective view ofthe lower or inner part or section of the button Fig. 5, a plan view of the same, and Fig. 6 a crosssectional view through the shank thereof'.

Theletter A indicates the outer part or section of my button, which may be termed the face,77 the saine being of any approved conguration or design, and of any suitable material. Securely connected with or united to this portion is a pin or stud, a, which is provided with a screw -thread, and which is slightly pointed or rounded at its lower extremity, for a purpose hereinafter named.

The letter B indicates the lower or inner section of my button, commonly known as the back,7 and which consists of a disk, b, having a shank or extension, C, formed therewith, or otherwise fastened thereto, which isof such length as to extend entirely through the folds of the cuff or other garment. The end of this shank G-is provided with or formed into an approximately elliptical head,c, to conform to the configuration of the button-hole, and is centrally bored and screw-threaded, as shown in the drawings, the mouth of the hole being flared outwardly or enlarged in diameter, the object of which is to admit of the more easy and ready connection of the parts by permitting the threaded pin a, pointed as above described, to enter well into the bore of the shank before the respective threads'take into each other. By this construction the use of my button is greatly facilitated, for as the pin is usually very short, and consequently partly hidden from view by the fingers in grasping the face of the button, it would otherwise be difficult to start the pin straight into the bore and to make the threads unite without binding or twisting. The elliptical head c, being shaped to conform to the button-hole, is easily passed therethrough, the conjugate diameter thereof being placed to coincide with that of the hole, and the diameter of the shank being greatly reduced, no difficulty is experienced in using the device, and no rumpliug or injury is occasioned to the cuff. The next object iu thus increasing the diameter of this head in one direction and decreasing it inthe other is to form a means of sustaining the back of the button in position while the connection is be ing made between it and the face thereof, and which at the saine time effectually holds the cuff during this operation.

In some instances I construct the shank C of a triangular or square form in its cross-section, as seen in Fig. 6, the object being to prevent it from revolvingin the button-holes while the pin a is being screwed thereto.

In applying my button to a cuff or collar or other garment I place the larger diameter of the head c to agree with that of the button-hole, and then press the head through the hole and turn it a quarter of a revolution, when it will be found to retain itself securely in position. The face of the button is then applied by inserting the pin a into 'the flaring mouth ofthe bore in the shank C until the threads meet, when the button-face is revolved and the connection made. It will be observed that as the head cis somewhat pointed it will be made the more readily to enter the button-hole by inserting one of its points into the same and then forcing it through in a wedge-like manner, thus avoiding unnecessarily spreading the button-hole.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a cuff or collar button, of a face-piece having a screw-threaded pin rounded at its outer end, with a back piece In testimony whoreofI affix my signature, in consisting of a disk, a shank internally bored presence of two Witnesses, this 27th day ofJanand threaded, as shown, and an approximately nary, 1882. elliptical head, substantially as shown and de- 5 scribed. DAVID LUBIN.

2. In a cuff or collar button, a back piece consisting of a disk, a shank of a triangular or Witnesses: square formin cross-section, provided with a H. AUBREY TOULMLN, liar-ing threaded bore, and an approximately J. J. MOGARTHY.

1o elliptical head, for the purposes herein set forth.
